Okay, one: *cackles madly at all the barrels pointed at your opponent* I *hiccup* want!
*sniff, cough* Okay, two: Skavenslaves. They're cheap, expendable, have a rule that allows you to shoot through (or rather, into them, and so at the enemy unit they're fighting), can help your army get into range as well as guard flanks (depending on wheat sort of army you're facing), and they do terrific things when they finally break.
Three: *facepalm* I suddenly realize that the second bit was actually the name for the rule mentioned in the third bit. Oh well, I'd rather write this than go back and fix it. It makes the point, after all.
Just my two bits. Give it some thought if you haven't already.
Your enemy is never a villain in his own eyes. This may offer you a way to make him your friend. If not, then you can kill him without hate--and quickly.
